Leather Care & Cleaning
Is Baking Soda Safe to Use on Leather?
Baking soda is mildly alkaline and abrasive as a paste, and leather is naturally acidic. When sources still use it, and what to use instead.
Not as a paste or scrub. Baking soda (sodium bicarbonate) dissolves into a mildly alkaline solution, while leather is naturally acidic, and Canada's conservation institute says alkaline saddle soaps are harmful to it for that reason. A shoe-care retailer warns that repeated use can dry leather out and cause cracking.
The one use some sources defend is a dry sprinkle on a fresh grease spot, brushed off after several hours. Even there, sources disagree, so test a hidden area first. This answer is part of our leather care and cleaning guide.
Why baking soda is risky on leather
- It is alkaline. A baking soda solution is mildly alkaline. A care maker says alkali damages genuine leather.
- It is abrasive as a paste. A maker recommends baking soda with minimal water as a gentle scouring powder. Scouring is what you don't want on a leather finish.
- It gets into the surface. The shoe-care retailer says the powder can seep into small cracks and wear the material over time.
When sources do use it
Baking soda is often claimed to remove odors, but an encyclopedia entry notes there is little evidence for that use.
| Use | What the source says | Our take | Facts |
|---|---|---|---|
| Dry sprinkle on a grease stain (furniture) | Sprinkle, leave several hours, brush off gently | Disputed; test first | – |
| Odors in faux leather | Scatter on, leave several hours to a day | Faux leather is a plastic coating, not hide | – |
| Paste scrub on real leather | Repeated use can dry and crack leather | Avoid | – |
What to use instead
- Fresh grease: a motorcycle brand sprinkles cornstarch or talcum powder on the stain, leaves it several hours or overnight, then brushes it off without rubbing.
- Everyday dirt: a damp, not dripping, cloth; don't rub hard.
- Faux leather: follow how to clean faux leather.
- Serious stains: see a professional leather cleaner.

Already used baking soda and see a dark spot?
Stop rubbing. Brush off any powder, wipe the area once with a barely damp cloth, and let it dry at room temperature. If the mark stays, a professional leather cleaner can assess it.
